OSCAR A. SMITH, OF EAST CLEVELAND, OHIO.

PBIMING CUP.

Application filed March 1, 1921. Serial No. 448319;

T 0 all whom it may concern.

Be it known'that I, OSCAR A. SMITH, a citizen ofthe UnitedSt-ates, residing at East Cleveland, in the county of Cuyahoga and State of Ohio have invented certain new and useful Improvements in Priming Cups, of which the following. is a specification.

This invention relates to priming cups for internal Combustion engines an object thereof being to provide an improved test or priming cup for admitting or introducing a priming fluid such as gasoline into the cylinder of the engine and which cup can be manufactured readily at a minimum of expense, and will be effective and durable in use.

A further object of this invention is to provide a priming cup having a valve openable in the, direction of flow of the fluid and controlled in itsoperation through the medium of acup or fluidreceiving chamber the latter being carried by the body portion of the device, and adapted to be shifted relatively thereto for opening or closing the valve. v i

A further object of this invention is to provide a priming device wherein the fluid receiving chamber or cup portionis threaded exteriorly to the body of the device and shiftablm'by rotating the same in successive directions, to open and close the valve.

Ar further object oi' this invention is to provide a priming device comprising. an axially bored body member'terminating in a valve seat, and a valve cooperating therewith. and having its stem connected or se cured to the fluid receiving chamber or cup interiorly thereof.

Other objects of this invention [will appear in the following description thereof, reference being hadto the accompanying drawing forming a part of this specification wherein" like reference characters indicate corresponding parts in the severalKviews and wherein Fig. 1 is aside elevation of my improved priming cup with the valve open; Fig. 2 is a sectional view "thereof; Fig; 3 is a sectional view similar to Fig. 2 with the valve closed; Fig. 41 is a top plan view of" this primingciipg' Fig.- 5 is a per;-

spective view thereof, parts being removed; Fig. 6 is a perspective view of the valve and stem; and Fig. 7 is a perspective view of the valve cup member.

In its preferred form herein shown and described my improved test or priming cup although particularly constructed for use with internal combustion engines, is or course adapted to be used for various other purposes, and comprisesa body member 10, drilled to form an axial passage-way therethrough, and provided at its lower end with straight right-hand threads 12 to permit the device to be attached to the cylinder head. At its upper end the body member 10 is provided eXteriorly thereof preferably with straight left-hand threads 11, the central portion 13 of the body being angularly formed forthe reception of a wrench. The '70 body member 10 adjacent to its upper end is chambered or counter-bored, as at 1 1, to

permit greater freedom for the flow of the gasoline or other fluld to the valve.

The valve member 111 this primmg devlcc .cohrprises the usual elongated stem 15 terminating at one end in a valve 16, which in v the present. embodiment is shown as a tapered valve adapted to cooperate with the valve seat 17 formed at the lower end. of so the body member 10. In the present instance the valve seat 17 is shown as having straight walls. but it willbe understood that the same may be provided with tapered walls or faces conforming substantially to the taper ofthe valve 16, such for instance as illustrated in my Patent No. 1,153,457, dated Sept lt, 1915.

My improved priming device is provided with a fluid receiving chamber or cupshaped member 18 formed interior-1y thereof with the chamber 19 for the reception of the priming I'i'uid. The cup 18 has interior threads 20 coope'ating with the exterior threads 11 of the body member 10, and is provided intermediate its depth with abushing 21., spun or otherwise secured therein.

J This bushing 21 is adapted to. form a base for the priming. cup and the portion 23 of the stem 15 is fastened or secured in any oo suitable way to the center 22 of the bushing In" order to permit the passa-ge-of'the way may be provided for the flow of the fluid from the cup to the valve.

Thus it will be seen that I have provided a primmg device wherein the fluid receiving chamber is shiftable exteriorly of the body member, and by virtue of the fact that the valve is connected to the chamber interiorly thereof, the same will be opened and closed upon shifting the chamber in successive directions relatively to the body member. Furthermore the cup or chamber is shiftable to open the valve in the direction offlow of the fluid, and hence because of the fact that the valve opens downwardly,the possibility of carbon orsoot clogging the parts or interfering with their operation is eliminated.

Although I have described my invention in its preferred form it is to be understood that I do not limit myself to the construction herein shown and described except in so far as defined in the claims and embraced within 7 the scope thereof.
